Filed:

Apr 8, 2003

Appl. No.:

10/409515

Inventors:

Michael L. Fripp - Carrollton TX, US
Roger L. Schultz - Aubrey TX, US
John P. Rodgers - Trophy Club TX, US

Assignee:

Halliburton Energy Services, Inc. - Houston TX

International Classification:

E21B 47/00

US Classification:

16625001, 3408543, 3408544

Abstract:

Thin flexible piezoelectric transducers are bonded to or imbedded into oilfield tubular members or structural members. The transducers may be used to telemeter data as acoustic waves through the members. By proper spacing of transducers and phasing of driving signals, the transmitted signals can be directionally enhanced or encoded to improve transmission efficiency. The transducers may be used for health monitoring of the tubular or structural members to detect cracks, delaminations, or other defects. The flexible transducers are very thin so that overall dimensions of tubular or structural members are essentially unchanged by incorporation of the transducers.

International Classification:

E21B 43/00

US Classification:

166 651, 290 54

Abstract:

An enhanced electrical power generating system. In a described embodiment, an electrical power generating system for use in a subterranean well includes a flow passage formed through a tubular string in the well, a flow region in communication with, and laterally offset relative to, the flow passage, an electrical power generator operative in response to flow of fluid through the flow region and multiple flow restrictors in the flow passage. The flow restrictors are operative to influence at least a portion of the fluid to flow from the flow passage through the flow region.

E21B 33/10

US Classification:

1663081, 1662552, 166179, 175 45

Abstract:

A method of servicing a well bore comprises deploying into the well bore a zonal isolation device operable to self-set at a sensed location, and self-setting the zonal isolation device to hold at the sensed location without receiving command communications from the surface, wherein the zonal isolation device is deployed along at least a partial length of the well bore via an external force. Another method of servicing comprises deploying into the well bore a tool operable to self-activate at one or more locations, and self-navigating the tool to determine the one or more locations without receiving communications from the surface, wherein the tool is moved along at least a partial length of the well bore via an external force.

US Classification:

166 66, 1662552, 1662541, 1662551

Abstract:

A downhole tool for use in a well bore comprises an onboard navigation system for determining the location of the tool within the well bore, wherein the tool is moved along at least a partial length of the well bore via an external force. A method of locating a downhole tool in a well bore comprises deploying the tool along at least a partial length of the well bore via an external force, and self-determining the location of the tool without receiving communications from the surface. In an embodiment, the tool is a well bore zonal isolation device.

US Classification:

310346, 310322, 310334, 310337

Abstract:

Thermal expansion matching for an acoustic telemetry system. An acoustic telemetry system includes at least one electromagnetically active element and a biasing device which reduces a compressive force in the element in response to increased temperature. A method of utilizing an acoustic telemetry system in an elevated temperature environment includes the steps of: applying a compressive force to at least one electromagnetically active element of the telemetry system; and reducing the compressive force as the temperature of the environment increases.
